Paul,

Have you configured HTTP Filtering on the ASA. If so, check out the "Truncating Long HTTP URLs" section under "Filtering HTTP URLs":

http://www.cisco.com/univercd/cc/td/doc/product/multisec/asa_sw/v_70/config/filter.htm#wp1042519

Let me know if it helps.

Re: long url sites is block by cisco ASA

Hi Arul,

I am not sure the settings is configured as it was handover by another engineer. but when I am trying to use the command, i get this:

pixfirewall(config)# filter url longurl-truncate ^

ERROR: % Invalid input detected at '^' marker.

so, i do this, 172.16.160.18 is my internal proxy server, i get this:

pixfirewall(config)# filter url 80 172.16.160.18 255.255.255.255 0.0.0.0 0.0.0$

No url servers found! Use "url-server" first.

what must I do to allow long URL?

Thanks and regards,

Paul
